For this case we propose a rule of three, in order to know the original price of the bicycle:
$ 93 ----------------> 60%
x ---------------------> 100%
Where the variable "x" represents the original cost of the bicycle. So:
[tex]x = \frac {100 * 93} {60}\\x = \frac {9300} {60}\\x = 155[/tex]
Thus, the original cost of the bike was $ 155
ANswer:
$155
